Lucas said the city is concerned that people could grow marijuana for their personal use in warehouses on agricultural land on a large scale.

“The proposed amendment would not be regulated by the Marijuana Enforcement Division and no local regulations have been identified to provide protections,” said Andy Firestine, deputy director of community development for the city, in an e-mail. “Also, no considerations have been made as to the enforcement of a co-op grow land use.”

Carl said he doesn’t understand Centennial’s concerns. He said there would be no such warehouses, but at the most greenhouses on these properties.

“The same limitations that would apply to someone growing their own marijuana at home would happen at this agricultural facility,” Carl said.

Lucas said the city is concerned about possible public safety hazards at potentially large grow operations at the borders of the city, for which the amendment in current form supplies no regulations.

The county planning commission votes on the amendment to the marijuana code June 3. If approved, the county commissioners vote June 24.

Carl said the impetus for the amendments was a desire from agricultural property owners to use their land for personal marijuana growing and that it would be a “win-win” because it would get marijuana growing out of the residential areas where he said he has heard complaints.

But Lucas said the city doesn’t agree.

“I hope the district commissioners that cover Centennial are listening,” Lucas said. ” I think they got the message fairly clear: We don’t want it on our borders, We don’t want it in our county.”
